SPECIFICATION formingpart of Letters Patent No. 739,724, dated; September 22, 1903.

Application filed March 4, 19ll2.

To aZZ whom it may concern: 7

Be it known that I, CHARLES C. SANDERS,

of Griffin, in the county of Spalding, State of Georgia, have invented certain new and use- I ful Improvements in Grates, of which the following is a complete specification, reference being had to the accompanying drawings.

The object of my invention is to produce an improved grate.

My invention is applicable to grates generally, but is particularly adapted for use in open fireplaces, where the comparatively small space provided for the accommodation of a fire makes it necessary that maximum radiation of heat be produced with minimum consumption of fuel and that in whatever amount of space be available.

In the accompanying drawings, Figure l I is a perspective view of a preferred form of a fireplace of usual type.

embodiment of my invention as applied to Fig. 2 is a vertical section of the subject-matter of Fig 1. Fig. 3 is a perspective view of a modified form of grate, showing clearly the shape of the bottom bars. Fig. 4: is a detail view of a further modification, illustrating the detachable back bar adapted for use in connection with the grate shown in Fig. 8.

Referring to the numerals on the'drawings, 1 indicates the back wall of a fireplace, of any ordinary or preferred construction, and 2 the side walls thereof.

3 indicates; horizontal cross-bars, of which four are shown, curved, approximately, at their ends and terminating in an upright 5, with which they are preferably made intogral. The upright 5 is provided with hooked members 6, extending from it in the plane of the bars 3, adapted to engage lugs 8, projectmg outwardly from the side walls 2 of the fireplace and by engagement therewith to support the front of the grate in proper relative position.

In the form of embodiment of my invention illustrated'the upright 5 extends below the bars 3 and terminates in a leg 9, which is adapted in the absence of the lugs 8 or hooked members (i to support the front of the grate. It may be specified, however, that the leg 9' may be omitted, if desired, and the grate supported solely by the means hereinbefore pointed out. The means of support Serial No. 96,628. (No model.)

for a grate represented by the hooks 6 and the uprights 5, extended to form legs 9, as specified, are located, as illustrated in Fig. 2, midway between the horizontal outwardlycurved cross-bars 3 and the back bar 15, thereby providing means for equally distributing the weight of the fuel-supply upon the bottom bars 10 and tending to properly balance the weight of the loaded grate.

Extending rearwardly from the bottom cross-bar 3 I provide bottom bars 10. The bottom bars 10 are of a diamond shape in cross-section and are inclined downwardly from the cross-bar 3, terminating at the ends opposite the cross bar in a back bar 15. The back bar 15 is secured in place by any suitable or preferred means and forms when thus secured a rigid support for the back of the grate.

In practice 'I prefer to form the various members hereinbefore specified as forming my grate integrally, as by casting or other preferred means, the conformation of the various members and the inclination or angle of the bottom bars being determined and adjusted at the will of the operator.

Referring to Figs. 2 and i, I illustrate a modified form of grate which may at times be used to advantage. In those figures I show the bottom bars as provided with hooked extremities 11, adapted to engage notches in the back bar 15. It will be readily apparent that the use of this form of grate will be de sirable at times, in view of the comparative ease with which'the back bar may be placed in position and the hooked extremities of the bars 10 adjusted in the notches 14. It may be also specified that when desired the notches on the bar 15 may be omitted; but these are merely details of manufacture and use, to be determined according .to conditions which may prevail, which are within the scope of the principle of my invention, but towhich I do not desire to limit myself.

In operation it may be stated, in addition to what has been already specified, that when the grate is in place-as, for instance," in a fireplace-the inclination of the bars 10 affords a large area of exposed fire-surface to the area to be heated. By the same means constant and strong draft is supplied to the fuel, tendingto maintain at all times a constant and
